Construction costs are currently skyrocketing

You are seeing it wrong - this is supposed to create an incentive for both parents not to be out of work for so long. If the daycare also costs (a lot of) money, you prefer to stay at home right away. At least 2 years, rather more.

It was said that we Germans have too few children.

I believe the Japanese basically have a different mentality. The social environment educates there. However, I don't want that here any more than Singaporean measures.

So you prefer dirty gravel pits and littered and graffiti-covered inner cities?

How quickly a yield curve can change is currently very clearly seen in the USA. The real estate market there is basically on the ground after interest rates for 30-year mortgage loans have risen to 6.13 percent.

Thus, interest rates there have roughly doubled since the beginning of the year. In Germany, however, they have tripled. There is no end in sight.

That will brutally affect rental prices, won't it? A) less construction b) more people, less living space c) those who build have to rent higher due to increased financing costs Is that really good for anyone?

Well, the homeownership rate in the USA has decreased from 68 to 61 percent since the 2008 financial crisis. The homeownership rate will likely decrease again in Germany as well.

This will brutally impact rental prices, won't it? A) less construction b) more people, less housing c) the one who builds has to rent higher due to higher financing costs

Is that really good for anyone?

For savers, this is good because they are finally receiving interest on their deposits again. For years, the media explained how German savers lose billions due to the zero-interest policy and how this makes their retirement provision worthless. (Info: that was sarcasm/irony)

I was stunned yesterday when I saw that from 2023 landlords will have to share parts of the CO2 tax with their tenants - depending on the energy level of the property.
